By together do you mean fully built up? Or like keep the legos together so you can rebuild the set later?

Keep it together for all perpetuity lol. At least for the Christmas stuff.
Ah ok. I had to clarify because when I buy my son Lego sets, after they get put together the first time, the pieces all immediately get added to the heap, never to be reassembled into the official kit again 🤣
